PEG MGF vs IGF-1 LR3
PEG MGF is cheaper per mg: $6.233 per mg at its best-priced strength, 2mg (PMF2, special order, 50-box minimum) against $20.464 per mg for IGF-1 LR3 at 1mg (IG1), 70 percent less. Every PEG MGF line is special order; from one box, IGF-1 LR3 at $20.464 per mg (IG1) is the only option. The two share no strength, and a milligram of one compound is not a milligram of the other, so these figures compare price, not amount of compound. PEG MGF is offered in 1 strength, IGF-1 LR3 in 2 (0.1mg to 1mg). Neither is on the shelf today. The least either takes: one box of IG1 at $204.64, against 50 boxes of PMF2, $6,233.00 of goods.

What differs between PEG MGF and IGF-1 LR3
Two lines from the same gene: a recombinant protein and a PEGylated peptide. IGF-1 LR3 is a single-chain 83-residue recombinant analogue of the whole hormone, full IGF-1 with an arginine at position 3 and a 13-residue N-terminal extension, and its sheet carries a defined mass of about 9,112. PEG MGF is a PEGylated conjugate of the 24-residue MGF E-peptide, and because the PEG polymer is polydisperse its sheet gives no single formula or exact mass, and identity is by ESI-MS. IGF-1 LR3’s certificate carries an endotoxin line, and PEG MGF’s, on the synthetic peptide specification, does not.

Questions
What is the difference between PEG MGF and IGF-1 LR3?
Two lines from the same gene: a recombinant protein and a PEGylated peptide. IGF-1 LR3 is a single-chain 83-residue recombinant analogue of the whole hormone, full IGF-1 with an arginine at position 3 and a 13-residue N-terminal extension, and its sheet carries a defined mass of about 9,112.
Which is cheaper per mg, PEG MGF or IGF-1 LR3?
PEG MGF, at $6.233 per mg for its best-priced strength, 2mg (PMF2, special order, 50-box minimum) against $20.464 per mg for IGF-1 LR3 at 1mg (IG1), 70 percent less. Every PEG MGF line is special order; from one box, IGF-1 LR3 at $20.464 per mg (IG1) is the only option. The two share no strength, and a milligram of one compound is not a milligram of the other, so these figures compare price, not amount of compound.
Which comes in more strengths, PEG MGF or IGF-1 LR3?
IGF-1 LR3, with 2 against 1. Every strength is a separate line with its own code, price and stock state.
Are PEG MGF and IGF-1 LR3 made to the same specification?
No. PEG MGF is released on an RP-HPLC purity of at least 98.0 percent and identified by mass, with no single calculated figure, its PEG being polydisperse. IGF-1 LR3, a recombinant protein, is released on RP-HPLC against the limit stated on its batch certificate and identified against the reference standard by the method that certificate names. Both carry net content within 5 percent of label and a retest date on the batch record.
